TRUCK.

Application filed April 2, 1926. Serial No. 99,222.

This invention relates to industrial trucks and pertains more particularly .to means for attaching thereto the tongues by which said trucks are guided and pulled.

It is an object of this invention to provide a construction which shall be simple to construct and easy to assemble, but which shall provide the necessary strength ant ruggedness to withstand the rough usage to which trucks of this type are frequently put.

Other objects and advantages-will appearhereinafter.

A preferred embodiment of the invention selected for purposes of illustration is shown in the accompanying drawings, in which,

Figure 1 is a perspective view illustrating one type of truck to which the invention may be applied.

Figure 2 the bolster and Figure 3 is an enlarged thereof.

The truck illustrated in Figure 1 is of the heavy duty type ordinarily constructed entirely of met-a1 and designed to carry very heavy loads. Trucks of this type receive very hard usage and it is essential that all of the parts be constructed to provide a maximum strength. While the invention hereinafter particularly described is chiefly adapted for such trucks, it may also be used to advantage in trucks of other types as will be understood by those skilled in the art.

The truck 's an enlarged top plan view of tongue construction.

side elevation frame 1 is carried on. rear wheels 2 and front wheels 3, the front wheels being mounted on axle 4L carried by the bolster 5. In order to provide maximum strength, the bolster 5, fifth wheel 6, and hounds 7, may be cast in a single piece, hounds 7 having a slot 8 therebetween to receive the tongue 9.

The tongue may be conveniently formed of a piece of T iron having a flange 10 adapted to fit within the slot 8 between the hounds. customarily the tongue has been secured to the hounds by means of a single bolt which received the entire pulling strain and also provided a pivot on which the tongue might swing vertically as desired. According to the present invention the tongue and hounds are provided with registering holes through which the bolt 11 may' pass, and in addition the hounds are provided with holes arranged rearwardly of the bolt 11 through which a second bolt 12 may pass.

The fiange 10 of the tongue is also provided with a slot 18 cooperating with the bolt 12 and adapted to permit the tongue to be swung vertically as in those cases where a single bolt is provided. Preferably, the slot may be arcuate, having its center ap proximately coincident with the axis of bolt 11. Due to the provision of the two bolts, the pulling strain,'when .the truck is moved, is taken at two points instead of at one, thus distributing the'strain which is applied both to the bolt and to the tongue.

In addition, the rear end of the tongue extends for a considerable distance within the slot between the hounds and is thus braced laterally to provide additional strength when it is sought to turn the truck.

In the preferred embodiment illustrated the slot 13 is open at the top to permit the raising of the tongue any desired distance. If desired, however, the slot may be closed to limit the upward movement of the tongue. Downward movementof the tongue, of course, is limited by engagement of the bottom of the slot 13 with the bolt 12.

It is to be understood that the invention may be variously modified and embodied within the scope of the subjoined claims.

I claim as my invention:

1. In a truck having a bolster in combination, a tongue, and means to pivotally secure saidton 'ue to said hounds comprising a pair of bolts passing therethrough, said tongue being provided with a slot cooperating with one of said bolts and a hole cooperating with the other bolt, said bolts and slot and hole being so spaced and arranged that pulling strain on said tongue is transmitted to the truck through both of said bolts.

2. In a truck having a bolster and hounds, in combination, a tongue, and means to pivotally secure said tongue to said hounds comprising a pair of bolts passing therethrough, said tongue being provided with an arcuate slot cooperating with one of said bolts and a hole cooperat-ingwith the other bolt, said bolts and slot and hole being so spaced and arranged that pulling strain on said tongue is transmitted to the truck through both of said bolts.

3. In a truck having a bolster and hounds, in combination, a tongue having a hole and a slot therein, and means for pivotally securing said tongue to said hounds comprising a pair of bolt-s passing through said hole and hounds and slot, said bolts engaging the Walls of both said hole and said slot when the tongue is in pulling position whereby pulling strain on said tongue is transmitted to the truck through both bolts.

4. In a truck having a bolster and hounds, in combination, a tongue having 21, hole and an arcuate slot therein, and means for pivotally securing said tongue to said hounds comprising a pair of bolts passing through name to this specification this 30th day of March, 1926.

ANSON J. BENTLEY.
